Description
本申请要求于2021年08月06日提交中国专利局、申请号为202110904533.2、申请名称为“定位方法和相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信领域,尤其涉及一种定位方法和相关装置。
定位是移动通信技术,例如第五代移动通信技术(5th generation mobile communication technology,5G)新无线(New Radio,NR),中的重要功能之一。其中,常见的定位方法包括基于时间测量的定位技术,包括下行到达时间差(downlink time difference of arrival,DL-TDOA),观察到达时间差(observed time difference of arrival,OTDOA)等。这种定位方法通过用户设备(user equipment,UE)测量多个小区基站下行信号到达UE的时间与参考小区基站下行信号到达UE的时间差(TDOA),来确定UE的位置。NR还定义了其他定位技术,例如基于离开角(angle of departure,AoD)的下行定位技术。在基于AoD的下行技术中,通过UE测量多个基站的下行信号得到的测量信息,推断和计算出各基站的AoD,从而基于多个基站的AoD来确定UE的位置。当前采用的一些定位方法需要UE参与测量,例如多站往返时间(multi-Round trip time,multi-RTT)定位方法、支持辅助全球导航卫星***(assisted-global navigation satellite system,A-GNSS)定位方法等等。
在需要UE参与测量的定位方法中,UE在参与定位测量的过程中能耗较高。如何降低UE在参与定位过程中的能耗是需要解决的问题。
发明内容
本申请实施例公开了一种定位方法和相关装置,以期降低UE的能耗。
第一方面,本申请实施例提供了一种定位方法,该方法包括:终端设备向接入网设备发送第一指示信息;所述第一指示信息用于请求进入非连接态做定位测量;或者,所述第一指示信息指示所述终端设备具备在所述非连接态做定位测量的能力;所述非连接态包括无线资源管理RRC非激活态或者RRC空闲态;所述终端设备在所述非连接态进行定位测量。所述第一指示信息用于请求进入所述非连接态。本申请中,终端设备在非连接态做定位测量的能力,可以包括在非连接态测量定位参考信号(PRS)的能力。
第一指示信息用于请求进入非连接态做定位测量。或者,第一指示信息指示终端设备具备在非连接态做定位测量的能力。这样接入网设备在接收到第一指示信息之后,了解到终端设备需要进入非连接态做定位测量或终端设备具备在所述非连接态做定位测量的能力,就会在满足将终端设备释放到非激活态的条件时,将终端设备释放到非激活态。可见,终端设备向网络设备发送第一指示信息,能够使得网络设备更快地将其释放到相应的非连接态,从而减少自身能耗。终端设备在非激活态做定位测量,能耗较低。
本申请实施例中,终端设备向网络设备发送第一指示信息,能够使得网络设备及时将其释放到相应的非连接态进行定位相关测量,从而降低自身能耗。
在一种可能的实现方式中,在终端设备向接入网设备发送第一指示信息之前,所述方法还包括:所述终端设备接收来自核心网设备的第二指示信息,所述第二指示信息指示所述终端设备进入所述非连接态做定位测量或者请求终端设备的位置估计。
在该实现方式中,终端设备接收来自核心网设备的第二指示信息。第二指示信息指示终端设备进入非连接态做定位测量或者请求终端设备的位置估计。终端设备根据第二指示信息就能知道可以进入非连接态做定位测量或位置估计。终端设备不必自己判断是否进入非连接态做定位测量或位置估计,处理量较少。终端设备按照核心网设备的指示(即第二指示信息)进入非连接态做定位测量或位置估计,能够避免终端设备自己决定进入非连接态做定位测量或位置估计不能满足定位业务需求的问题。
在一种可能的实现方式中,所述第二指示信息包含于请求位置信息(requestlocation information),所述请求位置信息用于请求所述终端设备做定位测量。
LTE定位协议(LTE positioning protocol,LPP)消息中的RequestLocationInformation(即requestlocation information)消息用于定位服务器向目标设备请求定位测量或位置估计。核心网设备(例如,定位服务器)可向终端设备发送requestlocation information来请求终端设备做定位测量或位置估计。可见,requestlocation information可用于请求终端设备做定位测量或位置估计。
在该实现方式中,第二指示信息包含于请求位置信息。请求位置信息用于请求终端设备做定位测量,该请求位置信息包含的第二指示信息指示终端设备进入非连接态做定位测量或者请求终端设备的位置估计。也就是说,请求位置信息可以达到两个目的,一个是请求终端设备做定位测量,另一个是指示终端设备进入非连接态做定位测量或者请求终端设备的位置估计。这样核心网设备就不必额外发送携带第二指示信息的消息,信令开销少。
在一种可能的实现方式中,所述方法还包括:所述终端设备向所述核心网设备发送第一能力信息,所述第一能力信息指示所述终端设备具备在所述RRC非激活态和/或所述RRC空闲态做定位测量的能力。
在该实现方式中,终端设备向核心网设备发送第一能力信息,以便核心网设备根据该第一能力信息获知终端设备具备在RRC非激活态和/或RRC空闲态做定位测量的能力。这样核心网设备就可以在某些情况下指示终端设备在非连接态做定位测量,终端设备就可以减少自身功耗。
在一种可能的实现方式中,所述第一能力信息包含于提供能力(providecapability)消息,所述提供能力消息指示所述终端设备具备的功能或能力。
LPP消息中的ProvideCapabilities(即providecapability)消息向定位服务器(例如核心网设备)指示目标设备(对应于终端设备)的LPP能力。终端设备可通过提供能力(providecapability)消息向核心网设备(即定位服务器)指示其LPP能力。
在该实现方式中,第一能力信息包含于提供能力消息。也就是说,终端设备向接入网设备发送的提供能力消息包含第一能力信息。终端设备不需要额外发送携带第一能力信息的消息,可以减少信令开销。
在一种可能的实现方式中,所述第一指示信息用于请求进入非连接态做定位测量;所述方法还包括:所述终端设备向所述接入网设备发送第二能力信息,所述第二能力信息指示所述终端设备具备在所述RRC非激活态和/或所述RRC空闲态做定位测量的能力。
在该实现方式中,终端设备向接入网设备发送第二能力信息,以便接入网设备获知终端设备具备在RRC非激活态和/或RRC空闲态做定位测量的能力,进而判断是否接受终端设备进入非连接态做定位测量。接入网设备获知终端设备具备在RRC非激活态和/或RRC空闲态做定位测量的能力之后,若终端设备请求进入RRC非激活态或者RRC空闲态做定位测量,则接入网设备就能够及时将其释放到相应的状态。
在一种可能的实现方式中,所述第二能力信息包含于用户设备能力信息(UE capability information)消息,所述用户设备能力信息消息用于指示所述终端设备具备的功能或能力。
在该实现方式中,第二能力信息包含于用户设备能力信息消息。终端设备将第二能力信息包含于用户设备能力信息消息,不需要额外发送携带第二能力信息的消息,可以减少信令开销。
在一种可能的实现方式中,所述第一指示信息包含于位置测量指示(location measurement indication)消息或者用户设备辅助信息(UE assistance information)消息,所述位置测量指示消息用于指示所述终端设备将要开始做定位相关的测量,所述用户设备辅助信息消息用于指示辅助信息。
位置测量指示(location measurement indication)消息用于指示UE(对应于终端设备)将要开始或停止位置相关测量。终端设备可通过位置测量指示消息指示将要开始位置相关测量,即将要开始做定位相关的测量。
UEAssistanceInformation(即UE assistance information)消息用于向网络指示UE辅助信息。终端设备可通过向核心网设备(对应于网络)发送包含第一指示信息的用户设备辅助信息。
在该实现方式中,第一指示信息包含于位置测量指示消息或者用户设备辅助信息消息。由于位置测量指示消息或者用户设备辅助信息消息本身也是终端设备需要向接入网设备发送的消息,因此第一指示信息包含于位置测量指示消息或者用户设备辅助信息消息,终端设备不需要额外发送携带第一指示信息的消息,可以减少信令开销。
在一种可能的实现方式中,所述位置测量指示消息或者所述用户设备辅助信息消息还包含所述终端设备决定的在所述非连接态下进行定位测量待采用的测量相关配置参数。
在该实现方式中,位置测量指示消息或者用户设备辅助信息消息还包含终端设备决定的在非连接态下进行定位测量待采用的测量相关配置参数,以避免接入网设备调度该资源给其他终端,从而避免对其执行的定位测量造成干扰。终端设备自行决定其在非连接态下进行定位测量待采用的测量相关配置参数,可以在满足定位业务需求的同时,尽量降低功耗。
在一种可能的实现方式中,所述测量相关配置参数包括一项或一项以上:测量的频点、测量的周期、测量的长度。
测量的长度可以包括测量的时间长度。

以下将详细介绍本申请涉及的网络架构。
本申请提供的技术方案可以应用于各种通信***,例如:长期演进(long term evolution,LTE)***、LTE频分双工(frequency division duplex,FDD)***、LTE时分双工(time division duplex,TDD)、通用移动通信***(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信***、第五代(5th generation,5G)通信***或新无线(new radio,NR)以及未来的其他通信***,如6G等。下面以5G通信***为例,介绍本申请提供的技术方案。
参见图1,图1是本申请提供的一种定位架构图的示例。如图1所示,定位架构图包括:接入网设备(例如gNB)、接入与移动性管理功能(access and mobility management function,AMF)实体、定位管理功能(location management function,LMF)实体以及终端设备(User Equipment,UE)。AMF实体是指具体AMF功能的实体(网元)。LMF实体是指具体LMF功能的实体(网元)。需要说明的是,在以下描述中,将AMF实体(即AMF的实体)简称为AMF,将LMF实体(即LMF的实体)简称为LMF。如图1所示,终端设备(即UE)与接入网设备通过NR-Uu接口通信,接入网设备之间通过Xn接口通信,接入网设备和LMF通过NG-C接口通信,LMF和AMF通过NL1接口通信。
定位管理功能LMF用于实现定位等功能。LMF是一种部署在核心网中为UE提供定位功能的装置或组件。本申请中,LMF实体可替换为其他为UE提供定位功能的装置或组件。在未来通信***中,如6G中,所述位置管理功能网元仍可以是LMF网元,或有其它的名称,本申请不做限定。
AMF,可用于对终端设备的接入控制和移动性进行管理。在实际应用中,其包括LTE的网络框架中移动管理实体(mobility management entity,MME)里的移动性管理功能,并加入了接入管理功能。AMF具体可以负责上述终端设备的注册、移动性管理、跟踪区更新流程、可达性检测、会话管理功能网元的选择、移动状态转换管理等。
接入网设备(例如gNB):一种部署在无线接入网中为UE提供无线通信功能的装置。接入网设备可以包括各种形式的宏基站、微基站(也称为小站)、中继站、接入点、可穿戴设备、车载设备。接入网设备还可以是传输接收节点(transmission and reception point,TRP)、传输测量功能(transmission measurement function,TMF)。接入网设备可以包括集成于接入网设 备上的中心单元(central unit,CU)和分布单元(distributed unit,DU)。

图1中的AMF和LMF为功能网元。本申请中,AMF实体和LMF实体可以是不同的通信装置;也可以是同一个通信装置(不同于接入网设备)。本申请中,AMF实体和LMF实体以及接入网设备可以是同一通信装置。
如背景技术所述,本领域技术人员正在研究已有下行定位技术的优化方案或者研究新的下行定位技术。本申请提供了能准确地将UE释放到相应的非连接态做定位相关测量的定位方法。
下面以先OTDOA定位为例介绍下行定位基本原理。OTDOA定位流程主要包括:定位中心(LMF)向UE附近的多个接入网设备(例如,图1中的NG RAN)请求用于OTDOA定位的配置信息;接入网设备将用于定位的配置信息(例如下行定位参考信号(positioning reference signal,PRS)的配置和其他接入网设备的信息)报告LMF;LMF将接入网设备的配置(例如下行定位参考信号的配置)向UE发送;LMF向UE发起定位信息测量请求;UE测量多个接入网设备的下行PRS到达UE的时间差完成测量并将测量信息发送定位中心。
由于本申请提供的定位方法涉及UE在非连接态做定位测量的相关内容。下面介绍UE的三种无线资源控制(radio resource control,RRC)状态。UE的三种RRC状态包括:RRC连接态(RRC CONNECTED态)、RRC非激活态(RRC INACTIVE态)、RRC空闲态(RRC IDLE态)。
RRC连接态:UE与接入网设备之间有RRC连接,并为UE建立了基站与核心网的连接。
RRC非激活态:UE与接入网设备之间的RRC连接被暂停(suspend),为UE建立了接入网设备与核心网的连接。
RRC空闲态:UE与接入网设备之间没有建立RRC连接,没有为UE建立接入网设备与核心网的连接。
为解决如何降低UE在参与定位过程中的能耗是需要解决的问题。本申请提供了新的定位方法。本申请提供的定位方法,能够更快地将UE释放到非连接态做定位相关测量,从而降低UE在参与定位过程中的能耗。本申请提供的定位方法适用于任何需要UE参与的定位方案,例如下行定位、multi-RTT定位方法、A-GNSS定位方法等等。
下面结合附图介绍本申请提供的定位方法。
图2为本申请实施例提供的一种定位方法交互流程图。如图2所示,该方法交互流程包括:
201、终端设备向接入网设备发送第一指示信息。
上述第一指示信息用于请求进入非连接态做定位测量。也就是说,第一指示信息指示终端设备请求进入非连接态做定位测量。或者,上述第一指示信息指示上述终端设备具备在上述非连接态做定位测量的能力。或者,上述第一指示信息用于请求进入非连接态。上述非连接态包括无线资源管理RRC非激活态或者RRC空闲态。本申请中,终端设备在非连接态做定位测量的能力,可以包括在非连接态测量定位参考信号(PRS)的能力。
在一种可选的实现方式中,上述第一指示信息包含于位置测量指示(location measurement indication)消息或者用户设备辅助信息(UE assistance information)消息。上述位置测量指示消息用于指示上述终端设备将要开始做定位相关的测量。上述用户设备辅助信息消息用于指示辅助信息。在一些实施例中,上述位置测量指示消息或者上述用户设备辅助信息消息还包含上述终端设备决定的在上述非连接态下进行定位测量待采用的测量相关配置参数。上述测量相关配置参数可以包括:测量的频点、测量的周期、测量的长度、时隙偏移(offset)等等。
202、终端设备在非连接态进行定位测量。
在一些实施例中,终端设备在非连接态进行定位测量之前,被接入网设备释放到非连接态。可理解,终端设备向接入网设备发送第一指示信息,便是为了更快地进入非连接态,从而在非连接态进行定位测量。也就是说,终端设备向接入网设备发送第一指示信息的目的是:接入网设备在满足将终端设备释放到非连接态的条件(例如终端设备没有数据业务)时,将终端设备释放到非连接态。换句话说,终端设备向接入网设备发送第一指示信息的目的是为了让接入网设备感知到终端设备的非连接态定位业务需求,即在非连接态做定位测量的需求。
在一些实施例中,上述第一指示信息用于请求进入非连接态做定位测量。也就是说,第一指示信息可指示终端设备请求进入RRC非激活态或者RRC空闲态做定位测量,接入网设备根据该第一指示信息可准确地将终端设备释放到相应的非连接态。例如,第一指示信息用于请求进入RRC非激活态做定位测量,接入网设备在接收到该第一指示信息之后,在满足将终端设备释放到RRC非激活态的条件时,将终端设备释放到RRC非激活态。又例如,第一指示信息用于请求进入RRC空闲态做定位测量,接入网设备在接收到该第一指示信息之后,在满足将终端设备释放到RRC空闲态的条件时,将终端设备释放到RRC空闲态。
在一些实施例中,上述第一指示信息指示上述终端设备具备在上述非连接态做定位测量的能力。也就是说,第一指示信息指示终端设备具备在RRC非激活态或者RRC空闲态做定位测量的能力。例如,第一指示信息指示终端设备具备在RRC非激活态做定位测量的能力,接入网设备在接收到该第一指示信息之后,在满足将终端设备释放到RRC非激活态的条件时,将终端设备释放到RRC非激活态。又例如,第一指示信息指示终端设备具备在RRC空闲态做定位测量的能力,接入网设备在接收到该第一指示信息之后,在满足将终端设备释放到RRC空闲态的条件时,将终端设备释放到RRC空闲态。
在一些实施例中,上述第一指示信息指示上述终端设备具备在RRC非激活态和RRC空闲态做定位测量的能力。在这些实施例,接入网设备在接收到该第一指示信息之后,在满足将终端设备释放到RRC非激活态(或RRC空闲态)的条件时,将终端设备释放到RRC非激活态(或RRC空闲态)。在这些实施例,接入网设备在接收到该第一指示信息之后,可以先将终端设备释放到RRC非激活态,经过一段时间后进一步将终端设备释放到RRC空闲态。
本申请实施例中,终端设备向网络设备发送第一指示信息,能够使得网络设备更快地将其释放到相应的非连接态,从而减少自身能耗。终端设备在非激活态做定位测量时,能耗较低。
图3为本申请实施例提供的另一种定位方法交互流程图。图3中的方法流程为图2中的方法流程的一种可能的实现方式。如图3所示,该方法交互流程包括:
301、LMF实体获知终端设备的第一能力信息。
步骤301一种可能的实现方式是:终端设备向LMF发送第一能力信息。
上述第一能力信息指示上述终端设备具备在上述RRC非激活态和/或上述RRC空闲态做定位测量的能力。上述第一能力信息可包含于提供能力(providecapability)消息,上述提供 能力消息指示上述终端设备具备的功能或能力或LPP能力。
具体来说,终端设备发送的providecapability消息一种举例:终端设备发给LMF实体的providecapability消息的NR-DL-PRS-ProcessingCapability信元中,包含supportedState信元。supportedState信元的取值为inactive或idle或outofConntected。该举例的代码示例如下:
[
SupportedState ENUMERATED{inactive,idle,outofConntected,…}
]
在该代码示例中,SupportedState表示在NR-DL-PRS-ProcessingCapability信元包含的supportedState信元。supportedState信元的取值为inactive、idle或者outofConntected。若supportedState信元的取值为inactive,则表示终端设备具备在RRC非激活态做定位测量的能力;若supportedState信元的取值为idle,则表示终端设备具备在RRC空闲态做定位测量的能力;若supportedState信元的取值为outofConntected,则表示终端设备具备在RRC非激活态和RRC空闲态做定位测量的能力。在实际应用中,终端设备可配置supportedState信元的取值,以便LMF实体通过providecapability消息获知终端设备在非连接态测量PRS的能力。
终端设备发送的providecapability消息的另一种举例如下:provide capability消息的NR-DL-PRS-ProcessingCapability信元中,包含supportInactiveState信元和/或supportIdleState信元。该举例的代码示例如下:
[
supportedInactiveState ENUMERATED{true,…},
supportedIdleState ENUMERATED{true,…},
]
在该代码示例中,supportedInactiveState表示NR-DL-PRS-ProcessingCapability信元中包含的supportedInactiveState信元,supportedIdleState表示NR-DL-PRS-ProcessingCapability信元中包含的supportedIdleState信元。supportedInactiveState信元的取值可以是true。若supportedInactiveState信元的取值是true,表明终端设备具备在RRC非激活态做定位测量的能力,否则,表明终端设备不具备在RRC非激活态做定位测量的能力。若supportedIdleState信元的取值是true,表明终端设备具备在RRC空闲态做定位测量的能力;否则,表明终端设备不具备在RRC空闲态做定位测量的能力。在实际应用中,终端设备可配置supportedIdleState信元的取值和/或supportedInactiveState信元的取值,以便LMF实体通过providecapability消息获知终端设备在非连接态测量PRS的能力。
步骤301的目的是使得LMF实体获知终端设备在非连接态测量PRS的能力,即在非连接态做定位测量的能力。应理解,终端设备可以通过其他方式使得LMF实体获知终端设备在非连接态测量PRS的能力,本申请实施例不作限定。例如,LMF实体可从接入网设备或者AMF实体获知终端设备在非连接态测量PRS的能力。步骤301是可选的,而非必要的。
302、LMF实体向终端设备发送第二指示信息。
上述第二指示信息可指示上述终端设备进入上述非连接态做定位测量。或者,上述第二指示信息可指示上述终端设备进入非激活态、连接态或者空闲态做定位测量。在一种可能的实现方式中,上述第二指示信息包含于请求位置信息,上述请求位置信息用于请求上述终端设备做定位测量。
在一些实施例中,LMF实体在确定终端设备在定位业务具有低功耗需求的情况下,向终端设备发送第二指示信息,以便节省该终端设备的功耗。在一些实施例中,LMF实体在确定 终端设备在非连接态做定位测量不能满足定位业务需求(例如精度要求等)的情况下,向终端设备发送第三指示信息。上述第三指示信息指示上述终端设备进入连接态做定位测量,在这种情况下,终端设备不执行步骤303和步骤304,在连接态进行定位测量。
在一些实施例中,第二指示信息指示上述终端设备在连接态做定位测量,则终端设备不执行步骤303和步骤304,在连接态进行定位测量。
303、终端设备向接入网设备发送第一指示信息。
步骤303的实现方式可与步骤201的实现方式相同。
304、终端设备在非连接态进行定位测量。
步骤304的实现方式可与步骤202的实现方式相同。
图3的方法流程中,LMF实体可以根据不同的定位业务需求来指示终端设备在不同的状态(RRC非激活态、RRC空闲态或者RRC连接态)做定位测量。例如,对于需要低功耗的定位业务,LMF可以推荐终端设备进入非连接态做定位测量。而对于某些高精度低时延的业务,LMF可以推荐终端设备保持在连接态做定位测量和上报。这样保证了不同定位业务需求下的指标。
本申请实施例中,LMF实体向终端设备发送请求位置信息,以便该终端设备准确地进入连接态做定位测量,能够节省该终端设备的功耗。
图4为本申请实施例提供的另一种定位方法交互流程图。图4中的方法流程为图2中的方法流程的一种可能的实现方式。如图4所示,该方法交互流程包括:
401、LMF实体向终端设备发送请求位置信息。
请求位置信息(requestlocation information)用于请求上述终端设做定位测量,例如测量下行定位参考信号。
402、终端设备向接入网设备发送位置测量指示消息。
上述位置测量指示(location measurement indication)消息用于指示上述终端设备将要开始做定位相关的测量。位置测量指示消息中包含第一指示信息。上述位置测量指示消息中包含的第一指示信息三种可能的形式如下:a)、上述第一指示信息用于请求进入非连接态做定位测量;b)、上述第一指示信息指示上述终端设备具备在上述非连接态做定位测量的能力;c)、上述第一指示信息请求进入非连接态。本申请实施例中,位置测量指示(location measurement indication)消息可替换为用户设备辅助信息(UE assistance information)消息;还可以替换为新定义消息(例如位置测量请求(location measurement request))或者其他已有的RRC消息,此处不限定。例如,步骤402替换为终端设备向接入网设备发送包含第一指示信息的用户设备辅助信息消息。
在一些实施例中,终端设备确定希望在非连接态做定位测量,(例如,终端设备确定在非连接态做定位测量满足定位业务需求,如精度要求等),向接入网设备发送携带第一指示信息的位置测量指示消息,以便在非连接态做定位测量。由于在非连接态做定位测量可节省终端设备的功耗,因此终端设备可优先选择在非连接态做定位测量。可选地,终端设备还可先判断在非连接态下做定位测量是否可满足定位业务需求(例如精度需求);若在非连接态下做定位测量可满足定位业务需求,则向接入网设备发送携带第一指示信息的位置测量指示消息;若在非连接态下做定位测量不能满足定位业务需求,则在连接态下做定位测量。在这些实施例中,终端设备既能满足定位业务需求,又能尽量减少自身功耗。
在一些实施例中,locationmeasurement indication消息用于指示终端设备要开始或者停止定位相关的测量。该消息中包括第一指示信息,可以表征终端设备希望进入特定RRC状态(例 如RRC空闲态)进行定位测量。
locationmeasurement indication消息中包括的第一指示信息表征终端设备希望进入特定RRC状态进行定位测量的一种举例为:location measurement indication消息中包括preferredRRCState信元(即第一指示信息),其取值可以是inactive、idle,或者outofConntected。preferredRRCState信元的取值为inactive表示终端设备希望进入RRC非激活态,preferredRRCState信元的取值为idle表示终端设备希望进入RRC空闲态,preferredRRCState信元的取值为outofConntected表示终端设备希望进入任意非连接态(即RRC非激活态或RRC空闲态中的任一种)。这种举例的代码示例如下:
[
PreferredRRCstate ENUMERATED{idle,inactive,outofConntected,…}
]
在该代码示例中,preferredRRCState表示locationmeasurement indication消息中包括的preferredRRCState信元。Inactive、idle、outofConntected表示preferredRRCState信元的三种取值。
locationmeasurement indication消息中包括的第一指示信息表征终端设备希望进入特定RRC状态进行定位测量的另一种举例为:location measurement indication消息中包括指示终端设备具备在非连接态做定位测量的能力的第一指示信息。例如,location measurement indication消息中包括supportedMeasruementRRCState信元,该supportedMeasruementRRCState信元的取值可以是inactive和/或idle。在该例子中,若supportedMeasruementRRCState信元的取值为inactive,则表示终端设备具备在RRC非激活态做定位测量的能力。在该例子中,若supportedMeasruementRRCState信元的取值为idle,则表示终端设备具备在RRC空闲态做定位测量的能力。这种举例的代码示例如下:
[
supportedMeasurementRRCState ENUMERATED{idle,inactive,…}
]
在该代码示例中,supportedMeasurementRRCState为location measurement indication消息中包括的supportedMeasruementRRCState信元。Idle和inactive表示supportedMeasruementRRCState信元的取值。
在一些实施例中,终端设备向接入网设备发送的位置测量指示消息还可以指示终端设备自行决定的在非连接态下进行定位测量待采用的测量相关配置参数。例如,测量相关配置参数包含测量的频点,测量的周期和时隙偏移(offset),测量的长度,等等。在一些实施例中,终端设备向接入网设备发送测量相关配置消息,该测量相关配置消息包含或指示终端设备自行决定的在非连接态下进行定位测量待采用的测量相关配置参数。
403、接入网设备在满足将终端设备释放到非连接态的条件后,将终端设备释放到非连接态。
在一种可能的实现方式中,接入网设备收到终端设备上报的位置测量指示消息后,在满足将终端设备释放到非连接态的条件后,接入网设备将终端设备释放到非连接态。接入网设备将终端设备释放到非连接态需要满足的条件可以包括:接入网设备接收到来自终端设备的上述第一指示信息。在一些实施例中,接入网设备将终端设备释放到非连接态需要满足的条件还可以包括:终端设备没有业务数据或者终端设备没有业务数据的时长大于时长阈值(例如1s、2s、5s等)。时长阈值可根据实际需求设置。在一些实施例中,接入网设备将终端设 备释放到非连接态需要满足的条件还可以包括其他条件,本申请不作限定。例如向终端设备发送RRC Release消息释放该终端设备进入非连接态。对于步骤402中a)形式的第一指示信息,接入网设备将终端设备释放到该终端设备所请求的RRC状态。对于b)形式的第一指示信息,接入网设备根据终端设备的能力信息,将终端设备在没有数据业务时释放到相应的RRC状态。如果终端设备具备在INACTIVE态和IDLE态做定位测量的能力,则接入网设备基于实现可以先将终端设备释放到INACTIVE态,一段时间后进一步释放到IDLE态。对于c)形式的第一指示信息,接入网设备在终端设备没有数据业务时将UE释放到相应的RRC状态。
404、终端设备进入非连接态完成定位测量,并将测量结果上报给LMF。
图5为本申请实施例提供的一种OTDOA定位原理示意图。UE的定位基本定位如图5所示:每两个eNodeB(一种接入网设备)确定一个双曲线定位区(例如,UE到eNodeB 0和eNodeB 1距离差为d0-d1构成一条双曲线,UE到eNodeB 0和eNodeB 2距离差为d0-d2构成另一条双曲线)。通过两条双曲线确定一个交点,并施以附加条件(如eNodeB自身地理位置信息)就可得到UE的确切位置。本申请中,终端设备可采用任意方式完成定位测量,例如图5中的定位方式。
405、LMF根据测量结果处理得到终端设备的位置。
图4的方法流程中,终端设备向网络设备发送位置测量指示消息来告知接入网设备,终端设备希望进入INACTIVE态或者IDLE态进行定位测量。由于位置测量指示消息是已有的RRC消息,因此图4中的方法流程能够较好地兼容已有的定位流程。
在一些实施例中,终端设备还可执行如下步骤:400、终端设备向接入网设备发送第二能力信息。
上述第二能力信息指示上述终端设备具备在RRC非激活态和/或RRC空闲态做定位测量的能力。该第二能力信息可以包含于终端设备向接入网设备发送的用户设备能力信息(UE capability information消息)中。该第二能力信息表征终端设备具备在非连接态(RRC非激活态或者RRC空闲态)测量定位参考信号(PRS)的能力。终端设备向接入网设备发送第二能力信息,以便接入网设备获知终端设备具备在RRC非激活态和/或RRC空闲态做定位测量的能力,进而判断是否接受终端设备进入非连接态做定位测量。
应理解,接入网设备还可采用其他方式获知终端设备在非连接态做定位测量(即测量定位参考信号)的能力上报给接入网设备,本申请不作限定。应理解,步骤400是可选的,而非必要的。图4中的方法流程的一些可能的实现方式可未包括步骤400。
本申请实施例中,终端设备向网络设备发送位置测量指示消息,既能让接入网设备感知到终端设备的非连接态定位业务需求,又能使得该网络设备准确地将其释放到相应的非连接态进行定位相关测量。
图6为本申请实施例提供的一种能力信息的交互流程。如图6所示,该能力信息的交互流程包括:601、接入网设备向终端设备发送用户设备能力查询(UE capability enquiry)消息,该用户设备能力查询消息用于查询终端设备具备的能力或功能;602、终端设备向接入网设备发送用户设备能力信息(UE capability information)消息,该UE capability information消息包含上述第二能力信息。
在一个例子中,UE capability information消息中的UE-NR-Capability信元中包含PRS-ProcessingCapability信元。在PRS-ProcessingCapability信元中包含supportedState信元,supportedState信元的取值为inactive(INACTIVE)和/或idle(IDLE)。第二能力信息这种举例的代码示例如下:
supportedState ENUMERATED{inactive,idle,…},
在该代码示例中,supportedState表示在PRS-ProcessingCapability信元中包含supportedState信元。在该举例中,若supportedState信元的取值为inactive,则表示终端设备具备在RRC非激活态做定位测量的能力;若supportedState信元的取值为idle,则表示终端设备具备在RRC空闲态做定位测量的能力。
在另一个例子中,UE capability information消息中的UE-NR-Capability信元中包含PRS-ProcessingCapability信元。在PRS-ProcessingCapability信元中包含supportInactiveState信元和/或supportIdleState信元。supportInactiveState信元表示终端设备具备在RRC非激活态做定位测量的能力。supportIdleState信元表示终端设备具备在RRC空闲态做定位测量的能力。UE capability information消息这种举例的代码示例如下:
supportInactiveState ENUMERATED{true,…},
supportIdleState ENUMERATED{true,…}
在该代码示例中,supportInactiveState表示PRS-ProcessingCapability信元中包含的supportInactiveState信元,supportIdleState表示PRS-ProcessingCapability信元中包含的supportIdleState信元。若supportInactiveState对应的取值为true,表示终端设备具备在RRC非激活态做定位测量的能力;否则,表示终端设备不具备在RRC非激活态做定位测量的能力。若supportIdleState对应的取值为true,表示终端设备具备在RRC空闲态做定位测量的能力;否则,表示终端设备不具备在RRC空闲态做定位测量的能力。
图7为本申请实施例提供的另一种定位方法交互流程图。图7中的方法流程为图6中的方法流程的一种可能的实现方式。如图7所示,该方法交互流程包括:
701、终端设备向LMF实体发送提供能力消息。
提供能力消息可指示终端设备具备在上述RRC非激活态和/或上述RRC空闲态做定位测量的能力。本申请实施例中,提供能力消息可参阅前面两种providecapability消息的举例。
702、LMF实体向终端设备发送请求位置信息。
在一些实施例中,上述请求位置信息包含第二指示信息。上述第二指示信息用于请求上述终端设备进入非连接态做定位测量。已有的请求位置信息用于请求终端设备做定位测量,未指示终端设备进入非连接态做定位测量。请求位置信息中包含的第二指示信息,用于指示终端设备可以进入非连接态(INACTIVE态或IDLE态)测量定位参考信号,即做定位测量。应理解,请求位置信息中包含的第二指示信息指示上述终端设备进入上述非连接态做定位测量,这样既能减少信令开销,又能准确地指示终端设备进入非连接态做定位测量。
请求位置信息中包含的第二指示信息的一种举例:requestlocation information消息的CommonIEsRequestLocationInformation信元中,包含suggestedRRCState信元,该suggestedRRCState信元得取值可以为inactive或idle或connected。requestlocation information消息的CommonIEsRequestLocationInformation信元中,包含的suggestedRRCState信元的代码示例如下:
[
suggestedRRCState ENUMERATED{inactive,idle,connected},
]
在该代码示例中,suggestedRRCState表示CommonIEsRequestLocationInformation信元中,包含的suggestedRRCState信元。suggestedRRCState信元的取值可以为inactive或idle或connected。若suggestedRRCState信元的取值为inactive,第二指示信息指示终端设备在RRC 非激活态做定位测量。若suggestedRRCState信元的取值为idle,第二指示信息指示终端设备在RRC空闲态做定位测量。若suggestedRRCState信元的取值为connected,第二指示信息指示终端设备在RRC连接态做定位测量。应理解,LMF实体可根据需要配置suggestedRRCState信元的取值,从而指示终端设备在相应的非连接态做定位测量。
请求位置信息包含的第二指示信息的另一种举例:requestlocation information消息的CommonIEsRequestLocationInformation信元中,包含的第二指示信息指示终端设备进入INACTIVE态/IDLE态做定位测量。例如,CommonIEsRequestLocationInformation信元中包含MeasureInInactive信元,和/或,包含MeasureInIdle信元。CommonIEsRequestLocationInformation信元中,包含的MeasureInInactive信元和MeasureInIdle信元的代码示例如下:
在MeasureInInactive信元和MeasureInIdle信元的代码示例中,MeasureInInactive表示CommonIEsRequestLocationInformation信元中包含的MeasureInInactive信元,MeasureInInactive信元的取值可以为true;MeasureInIdle表示CommonIEsRequestLocationInformation信元中包含的MeasureInIdle信元,MeasureInIdle信元的取值可以为true。若MeasureInInactive信元的取值为true,表示第二指示信息指示终端设备在RRC非激活态做定位测量;否则,表示第二指示信息指示终端设备不要在RRC非激活态做定位测量。若MeasureInIdle信元的取值为true,表示第二指示信息指示终端设备在RRC空闲态做定位测量;否则,表示第二指示信息指示终端设备不要在RRC空闲态做定位测量。应理解,LMF实体可根据需要配置MeasureInIdle信元的取值以及MeasureInIdle信元的取值,从而指示终端设备在相应的非连接态做定位测量。
在一些实施例中,第二指示信息可指示上述终端设备进入非激活态、连接态或者空闲态做定位测量。如果第二指示信息指示上述终端设备在连接态做定位测量,终端设备不执行步骤705,而是在连接态进行定位测量,并将测量结果上报给LMF。在这些实施例中,接入网设备不将终端设备释放到非连接态。也就是说,接入网设备不执行步骤704。
703、终端设备向接入网设备发送位置测量指示消息。
步骤703的实现方式可参阅步骤402的实现方式。
704、接入网设备在终端设备满足将终端设备释放到非连接态的条件后,将终端设备释放到非连接态。
步骤704的实现方式可参阅步骤403的实现方式。
705、终端设备进入非连接态完成定位测量,并将测量结果上报给LMF。
步骤705的实现方式可参阅步骤404的实现方式。图8为本申请实施例提供的一种位置信息交互流程图。如图8所示,该位置信息交互流程包括:801、LMF实体向终端设备发送请求位置信息(request location information);802、终端设备向LMF实体发送提供位置消息(provide location information),该提供位置信息可包含测量结果。
706、LMF实体根据测量结果处理得到终端设备的位置。
步骤706的实现方式可参阅步骤405的实现方式。
本申请实施例中,LMF实体向终端设备发送请求位置信息,以便该终端设备准确地进入连接态做定位测量,能够节省该终端设备的功耗,并减少信令开销。
图2和图4的方法流程描述了终端设备主动决定是否需要进入非连接态做定位测量的方案。终端设备根据定位业务需求以及自身状况(例如数据业务、功耗等)自行决定是否进入非连接态做定位测量,能够在满足定位业务需求的同时,尽量减少自身的功耗。图6和图7的方法流程中,LMF实体获取终端设备的能力信息,继而决定推荐终端设备在非连接态做定位测量。在一些实施例中,LMF实体可根据定位业务需求(例如低功耗需求)推荐终端设备在非连接态做定位测量,从而减少终端设备的功耗。也就是说,图6和图7的方法流程中,LMF可以根据不同的业务需求灵活的选择不同方式来满足不同业务的需求。下面介绍本申请实施例提供的一种由接入网设备决定是否将终端设备释放到非连接态的方法。
图9为本申请实施例提供的另一种定位方法交互流程图。图9的方法流程中,接入网设备决定是否将终端设备释放到非连接态,以便终端设备在非连接态做定位测量。如图9所示,该方法包括:
901、终端设备向接入网设备发送第二能力信息。
上述第二能力信息指示上述终端设备具备在上述RRC非激活态和/或上述RRC空闲态做定位测量的能力。上述第二能力信息可包含于用户设备能力信息消息(UE capability information消息),上述用户设备能力信息消息用于指示上述终端设备具备的功能或能力。步骤901的实现方式可参阅图4中的步骤400,用户设备能力信息消息可参阅上述UE capability information消息的举例,这里不再详述。
902、LMF实体向终端设备发送请求位置信息。
步骤902的实现方式可参阅步骤401的实现方式。
903、终端设备向接入网设备发送位置测量指示消息。
上述位置测量指示消息用于指示上述终端设备将要开始做定位相关的测量。
904、在满足目标条件的情况下,接入网设备将终端设备释放到非连接态。
上述目标条件包括上述终端设备没有数据业务,以及上述终端设备具备在上述非连接态做定位测量的能力。在一种可能的实现方式中,上述目标条件还包括:上述终端设备在上述非连接态做定位测量满足定位业务需求。上述目标条件还可以包括其他条件(例如定时器超时),本申请实施例不作限定。定时器超时可以是终端设备没有数据业务的持续时长超过定时器的定时时长。在一些实施例中,在满足目标条件的情况下,接入网设备向终端设备发送RRC Release消息以释放该终端设备进入非连接态。
905、终端设备进入非连接态完成定位测量,并将测量结果上报给LMF。
步骤905的实现方式可参阅步骤404的实现方式。
906、LMF实体根据测量结果处理得到终端设备的位置。
步骤906的实现方式可参阅步骤405的实现方式。
本申请实施例中,在满足目标条件的情况下,接入网设备将终端设备释放到非连接态,既能满足定位业务需求,又能降低终端设备的功耗。
